Establishing a radio link
Note the following points when you establish a radio link between the
transmitter and receiver.
Adjusting frequencies
To establish a radio link between the transmitter and receiver, the same
frequency must be set in both devices.
You can do this in a number of different ways:
1. Set a frequency in the receiving channel of the receiver (see „Frequency
menu item“) and synchronize it with the transmitter (see „Synchronizing
devices“).
2. Automatically allocate the frequencies using the Auto-Setup function
(see „Scan & Auto-Setup menu item“).
3. Set the frequency on the receiving channel of the receiver and on the
transmitter manually (EM 6000: „Frequency menu item“, SK 6000: „Op-
erating the SKM 6000 menu“, SK 6212: „Operating the SK 6212 menu“,
SKM 6000: „Operating the SK 6000 menu“).
Encrypting the radio link
For maximum data security, you can activate AES 256 encryption for the
radio link.
This function can be activated only on the receiver (see „Encryption menu
item“) and then has to be synchronized to the transmitter (see „Synchroniz-
ing devices“).
Meaning of the Link Quality Indicator
The LQI (Link Quality Indicator) on both EM 6000 displays shows the trans-
mission quality for the channel in question.
On the one hand, the transmission quality depends on the field strength
(RF indicator on the receiving channel display). However, on the other
hand, it also depends on external sources of interference that cannot be
identified on the RF indicator (for example, they may be on the same fre-
quency or a very close neighboring frequency or may not affect the RF
strength).
As a basic principle, an LQI value significantly higher than 50% should be
achieved for a secure transmission.
